Honeywell 40003916-01 Mechanical install.

I got a sore head trying to figure out why this won't fit?
Hopefully someone out there knows something.
I bought this unit as a straight replacement. Take one off put the other on, simple. No...
For some reason the slot doesn't line up properly with the valve.
Are there different styles i didn't know about albeit there both the same number.
When the new in is fitted it only springs back a short way. The valve moves freely without the actuated fitted. Grrrrrrrr
Thanks in advance

Did the one you took off have a dimple on the silver box?

 

[james69]

Ill have to check that tomorrow as i left it at work.
Is it different if it has

 

[james69]

Good mkrning folks.
Yes, thers a dimple?

It is necessary sometimes to move the manual lever over to align the spindle with the slot in the powerhead. The head you've got should fit the 2 port body. If you managed to remove it then it should be compatible.

I did get this back on but had to rotate the valve to line up with the actuator. now when i release the spring from manual it only closed by about a third?

I think this was down to lack of experance. I now believe the spring iy moves back partially and was fitted cirrectly first time around.
Now to re wire. Any tips?
